After peaking at 23,193 tons in 1970, cockle production plummeted to 11,735 tons in 1990 and 58 tons in 2020. Jeollanam-do production in 2020 is 56 tons. This is due to the beginning of mass export of more than 90% of the cockle production in Korea to China during the boom period of cockle farming in the mid-late 1990s. In addition, the cockle fish farms collect and sell fast-growing individuals during intensive harvesting, so high-quality species are gradually decreasing, and repeated breeding is made in small individuals. Accordingly, the Jangheung branch of the Jeollanam-do Institute of Oceans and Fisheries Science has been conducting selective breeding tests by artificial seed production from 2021, taking into account the genetic diversity of each region, such as Boseong Beolgyo, Goheung Namyang, and Chungnam Seocheon. It plans to invest 379 million won in the next 10 years. In the midst of this, in order to develop a fast-growing variety that is resistant to environmental ...
